FORM 2 THE PATENTS ACT 1970 [39 OF 1970] 8B THE PATENTS RULES, 2003 as amended by THE PATENTS (AMENDMENT) RULES, 2006 COMPLETE SPECIFICATION [See Section 10; rule 13] "AIR CLEANER STRUCTURE FOR VEHICLE" HONDA GIKEN KOGYO KABUSHIKI KAISHA., a corporation of Japan, having a place of business at 1-1, Minamiaoyama 2-chome, Minato-ku, Tokyo, Japan The following specification particularly describes the invention and the manner in which it is to be performed: preferable for extending the exchange interval of an air filter element, in order to provide a passage for an oil or the like in an air cleaner. [0002] [Prior Art] As an air cleaner structure for a vehicle comprising a breather device for refluxing a blow-by gas from a crankcase of an engine to an air cleaner, there has been known, for example, "Blow-by Gas Reflux Device for Multicylinder Engine"that which is described in Japanese Pre-examination Patent Publication (KOKAI) No. 7-119431 (1995) . [0003] The art of the above-mentioned publication, as shown in FIGS. 1 and 3 of the publication, resides in that a chamber 83 (The symbols used in the publication are used.) is formed by fitting a cover plate 79 to a front wall 74 of a front case 67 in a cleaner case 63 of an air cleaner 28 by a plurality of bolts 81, an intake tube 84 connected to a crankcase is connected to the chamber 83 to thereby communicate between the crankcase and the chamber 83, an oil mist flowing from the crankcase into the chamber 83 is discharged to the side of an element 64 through a communication hole 82 provided in a cover plate 79, and a water discharge hole 88 is provided at a lower portion of the chamber 83 to thereby discharge water and oil in the chamber 83 into the water discharge hole 88. [0004] [Problems to be solved by the Invention] According to the art of the above-mentioned publication, the oil separated in the chamber 83 by forming the chamber 83 is discharged by using the lower surface of the chamber 83 as an oil passage, so that formation of the chamber 83 as the oil passage needs the cover plate 79, the bolts 81, female screws for screwing the bolts 81, and boss portions for forming the female screws, and, therefore, the number of component parts is large, and structure is complicated. Therefore, a large number of assembly steps are needed. [0005] In addition, since the communication hole 82 communicating from the chamber 83 into the clean side of the air cleaner 28 is provided in the vicinity of the lower surface of the front case 67, the oil mist contained in the blow-by gass flowing through the communication hole 82 into the clean side flows to the side of the element 64 under the flow of air on the upper side in the clean side to adhere to the element 64, thereby presumably shortening the exchange interval of the element 64. [0006] Accordingly, it is an object of the present invention to simplify structure, reduce the number of component parts, facilitate assembly and prolong the exchange interval of an air filter element, in order to provide a passage for an oil or the like in an air cleaner, in an air cleaner structure for vehicle. [0007] [Means for Solving the Problems] In order to attain the above object, claim 1 is characterized in that, in a vehicle comprising an engine breather device for communication between a crankcase of an engine and an air cleaner by a piping, an air filter element is disposed at a predetermined upward spacing from a bottom surface of an air cleaner case faced to the inside of a clean side of the air cleaner, a passage is formed by surrounding with a lower surface of the air filter element, the bottom surface of the air cleaner case and two side walls of the air cleaner case, and a discharge port is provided at an end portion of the passage. [0008] The passage is formed in the inside of the clean side by the lower surface of the air filter element, the bottom surface of the air cleaner case and the two side walls of the air cleaner case, and the oil or the like is caused to flow through the passage to the discharge port, whereby the oil or the like can be discharged with a simple structure without forming a special passage in the air cleaner case. [0009] Besides, since it is needless to provide a chamber as in the conventional art, there is no need for bolts or a partition wall, the number of component parts can be reduced, and production cost can be reduced. In addition, fastening bolts for forming the chamber is unnecessary, the number of assembly steps can be reduced, assembly is facilitated^ and assembly cost can be reduced. [0010] Further, when the bottom surface of the air cleaner case is spaced by a sufficient distance downwards from the air filter element so that the oil flowing on the bottom surface of the air cleaner case does not adhere to the air filter element, the air filter element would not be stained with the oil or the like, and the exchange interval of the air filter element can be prolonged.

[0014] With the engine 13 started, the oil reserved in the crankcase 64 is raked up by the rotating crank shaft 65 and the swinging connecting rod 63, and forms an oil mist and droplets, which lubricate each portion in the crankcase 64. In addition, the oil mist flows through a communication hole (not shown) in the cylinder block 21 into the cylinder head 22, to lubricate each portion in the cylinder head 22. [0015] Then, the oil mist in the cylinder head 22 flows through the breather tube 72 into the air cleaner 18 as indicated by arrows under a positive pressure in the crankcase 64 and a negative pressure in the air cleaner 18. Further, the oil mist flows from the air cleaner 18 through the connecting tube 17, the carburetor 16, the intake pipe 15 and the intake port 67 into the combustion chamber 66 as indicated by arrows, and is burned, before being discharged through the exhaust port 71, the exhaust pipe 24 and the muffler 25 to the exterior. [0016] The above-mentioned breather tube 72 and the air cleaner 18 constitute a breather device 74 for refluxing a blow-by gas including the oil mist in the crankcase 64. [0017] FIG. 3 is a side view of the air cleaner according to the present invention; the air cleaner 18 is so constructed that an air filter element 77 is disposed in an air cleaner case 76, the connecting tube 15 is fitted to a front portion of the air cleaner 18 (the "front" side (front side of the vehicle, here and hereinafter) indicated by void arrow in the figure is the front portion of the air cleaner 18), an intake port 78 is provided at a rear lower portion of the air cleaner 18, and a drain tube 68 is extended from a rear portion of the air cleaner 18. [0018] FIG. 4 is a plan view of the air cleaner according to the present invention, and shows that the air cleaner 18 is so constructed that the air cleaner case 76 is constituted of a case main body 81 and a case cover 82 covering an opening portion of the case main body 81, the case cover 82 is fitted to the case main body 81 by small screws 83 • • • ( • • • means plurality, here and hereinafter), and the connecting tube 17 and the breather tube 72 are connected to the case main body 81. Incidentally, 85 denotes an intake duct communicating from the intake port 78 (See FIG. 3) into the air cleaner 18, 86 denotes a breather tube fitting pipe provided at the case main body 81 for connecting the breather tube 72 to the case main body 81, and 87 denotes a resonator provided at the connecting tube 17 for reducing intake sound. [0019] FIG. 5 is a sectional view taken along line 5-5 of FIG. 3, and shows that the air filter element 77 is disposed at a predetermined position of the case main body 81 in the air cleaner 18, and the case cover 82 is fitted to the case main body 81 so as to clamp the air filter element 77 therebetween. [0020] Where the case cover 82 is fitted to the case main body 81, a lower surface 77a of the air filter element 77, a bottom surface 81a and a side wall 81b provided at lower portions of the case main body 81, and a side wall 82a provided at a lower portion of the case cover 82 constitute an oil passage 90 as a passage for flow of an oil and water, particularly, the oil in the air cleaner 18. [0021] The width of the oil passage 90 is W which is the distance between the side walls 81b and 82a, the height of the oil passage 90 at maximum is HU which is the distance between the bottom surface 81a and a projected portion 82b, and the height of the oil passage 90 at minimum is HL which is the distance between the bottom surface 81a and the lower surface 77a (the predetermined spacing as set forth in claim 1). Here, 92 denotes a dirty side of the air cleaner 18, and 93 denotes a clean side of the air cleaner 18. [0022] As described above, the air filter element 77 can be fixed by simply clamping between the case main body 81 and the case cover 82 in the air cleaner 18. Thus, according to the present invention, fixation of the air filter element 77 and formation of the oil passage 90 can be performed at the same time, so that the number of component parts and the number of assembly steps can be reduced, production cost of the air cleaner 18 can be reduced, and productivity can be enhanced. [0023] The air filter element 77 is constituted of a filter paper 77b for removing dust, dirt and the like contained in air in the dirty side 92, a soft material 77c provided at the periphery of the filter paper 77 for flexibly supporting the filter paper 77, and an element holder 77d for holding the soft material 77c. [0024] The element holder 77d is formed in a frame shape for holding the soft material 77c, and is formed of a metallic sheet. While the element holder has conventionally been formed of a resin, when the element holder 77d is formed of a metallic sheet, the air filter element 77 can be made thin, the space in the air cleaner 18 can be utilized effectively, the air passage can be made larger, and intake efficiency can be enhanced. Further, the thickness (thickness in the vehicle width direction) of the air cleaner 18 can be reduced, and the vehicle width can be restrained from being enlarged. [0025] The projected portions 82b and 82c of the case cover 82 are so constructed that the soft material 77c of the air filter element 77 is pressed against them, whereby the air filter element 77 can be fitted between the case main body 81 and the case cover 82 without chattering, and dimensional errors of the portions of the case main body 81 and the case cover 82 clamping the air filter element 77 therebetween can be absorbed. [0026] FIG. 6 is a front view of the case main body according to the present invention; the case main body 81 is so constructed that the inside space thereof is partitioned by a partition wall 95 into a first partition portion 97 and a second partition portion 97, and the first partition portion 97 and the second partition portion 98 are mated respectively with a first partitioned portion and a second partitioned portion formed by partitioning the inside space of the case cover 82 (See FIG. 4) by a partition wall not shown, whereby a first chamber 101 is formed by the first partition portion 96 and the first partitioned portion, and a second chamber 102 is formed by the second partition portion 97 and the second partitioned portion. [0027] The first chamber 101 in which the air filter element 77 is disposed comprises a curved wall 104 for preventing the oil mist flowing in from the breather tube 72 (See FIG. 4) through the communication hole 103 from flowing toward the air filter element 77, a penetrating portion 105 provided in the curved wall 104 for jetting out the oil mist downwards, a first bottom surface 81d and a second bottom surface 81e constituting the bottom surface 81a of the case main body 81, and a discharge port 81q for discharging the oil flowing on the first and second bottom surfaces 81d, 81e. Symbols Blh, 81j, 81k and 81m denote positioning portions for positioning the air filter element 77, and symbol 81n denotes a connecting tube fitting hole for fitting the connecting tube 17 (See FIG. 4). [0028] In the condition where the driver does not ride on the motorcycle 10 shown in FIG. 1 and the stand 52 is used, in FIG. 6, the first bottom surface 81d is inclined rearwardly downwards by an angle 6 relative to a horizontal plane 107, and the second bottom surface 81e is further inclined rearwardly downwards than the inclination angle 6 of the first bottom surface 81d. [0029] The second chamber 102 is so constructed that it is provided with a small-diameter intake port 108 and a large-diameter discharge port 109, an intake-side tube (not shown) is connected to the intake port 108, the tip end of the intake-side tube is disposed in a gap of the vehicle body frame 42 (See FIG. 1), a secondary air control valve (not shown) is fitted to the discharge port 109, the secondary air valve is connected to a reed valve (not shown) provided at the cylinder head 22 (See FIG. 1) through a discharge-side tube, and connection is made from the reed valve to the exhaust port 71 (See FIG. 2). [0030] With such a constitution as above, air taken in from the above-mentioned intake-side tube into the second chamber 102 is filtered by an air filter not shown, the flow of the filtered air is controlled by opening and closing a secondary air control valve, and, when the secondary air control valve is opened, air is supplied to the exhaust port 71 through the reed valve to oxidize unburned gas in the exhaust gas, thereby cleaning the exhaust gas, and the cleaned exhaust gas is discharged to the exterior. The opening and closing of the secondary air control valve are performed by utilizing a negative pressure in the intake pipe 15. [0031] Symbol 111 denotes an endless form first seal member surrounding the first partition portion 96, 112 denotes a second seal member surrounding a part of the . second partition portion 97, and the first seal member 111 and the second seal member 112 are members fitted in grooves formed in mating surfaces of the case main body 81 and the case cover 82. The second seal member 112 is provided with end portions 112a and 112b, and the above-mentioned grooves at the mating surfaces are so formed that the end portions 112a and 112b come into close contact with the first seal member 111, whereby the second seal member 112 is provided with a seal function equivalent to that of an endless form seal member. Since the second seal member 112 is easier to produce than an endless form seal member, parts cost can be suppressed. [0032] FIG. 7 is a sectional view taken along line 7-7 of FIG. 3, and shows that the case cover 82 is provided with a curved wall 114 so as to surround the periphery of an edge portion of the curved wall 104 of the case main body 81 in the air cleaner 18, and the curved wall 114 is provided with a penetrating portion 115. With the curved walls 104 and 114, the oil mist flowing into the air cleaner 18 can be prevented from flowing to the side of the air filter element 77 (See FIG, 6) . [0033] FIG. 8 is a sectional view taken along line 8-8 of FIG. 6, and shows that the case main body 81 is provided with a recessed portion 81p recessed more to the inside of the vehicle body (in the direction of arrow "in") than the second bottom surface 81e, and an oil discharge port 81q is provided on the rear side of the recessed portion 81p. The discharge port 81q is for connecting the drain tube 68. [0034] FIG. 9 is a side view of a rear portion of a vehicle for illustrating the drain tube fitted to a rear portion of the air cleaner according to the present invention, and shows that an end portion of the drain tube 68 is fitted to the rear end of the power unit 12 by a clip 117, and the tip end of the drain tube 68 is closed with a plug 118. Symbol 121 denotes a band for fixing the plug 118 to the drain tube 68. [0035] Action or effect of the air cleaner structure described above will be described below. FIG. 10 is an action view for illustrating the action or effect of the air cleaner structure according to the present invention. The air cleaner 18 is so constructed that, as indicated by void arrows a to d, outside air is sucked in from the intake port 78 through an intake duct into the dirty side, is filtered by the air filter element 77, caused to flow into the clean side 93, and is caused to flow from the clean side 93 into the connecting tube 17. [0036] On the other hand, the oil mist flowing in from the inside of the cylinder head of the engine through the breather tube and the communication hole 103 into the air cleaner 18 flows through the penetrating portions 105 and 115 (for symbol 115, see FIG. 7) as indicated by arrows ® and (1), and flows into the connecting tube 17 together with the flow of air. [0037] In addition, a part of the oil mist becomes droplets of oil, which drop onto the first bottom surface 81d as indicated by arrow ®, the dropped oil flows on the inclined first bottom surface Bid as indicated by arrow @, further, flows from the first bottom surface Bid to the second bottom surface 81e as indicated by arrows (5) and ©, and flows from the second bottom surface 81e through the recessed portion 81p and the discharge port Blq (See FIG. 8) into the drain tube 68 as indicated by arrow (Z). Then, the oil accumulates in the drain tube 68 shown in FIG. 9. The oil thus accumulated is periodically discharged by removing the plug 118. [0038] Thus, in FIG. 6, the position of the communication hole 103 through which the oil mist is jetted from the breather tube 72 (See FIG. 4) into the air cleaner 18 is provided between the air filter element 77 and the connecting tube 17 and at an upper portion of the case main body 81, whereby it is possible to prevent the oil mist flowing from the communication hole 103 into the air cleaner 18 from flowing to the side of the air filter element 77 by the flow of air flowing from the side of the air filter element 77 to the side of the connecting tube 17 in the air cleaner 18, and the air filter element 77 can be prevented from being stained by the oil mist. [0039] Besides, since the oil passage 90 according to the present invention has a comparatively large width W as shown in FIG. 5, even when the quantity of the oil flowing on the bottom surface 81a is increased, the oil can be made to difficultly adhere to the filter paper 77b. Further, since the first bottom surface 81d and the second bottom surface 81e are surfaces inclined rearwardly downwards, the oil can be smoothly led to the discharge port 81q. [0040] As has been described referring to FIGS. 1, 2 and 5, in the motorcycle 10 comprising the breather device 74 for the engine 13 for communication between the crankcase 64 of the engine 13 and the air cleaner 18 through the breather tube 72, the air filter element 77 is disposed at the predetermined upward spacing HL from the bottom surface 81a of the air cleaner case 76 fronting on the inside of the clean side 93 of the air cleaner 18, the oil passage 90 as a passage is formed by surrounding by the lower surface 77a of the air filter element 77, the bottom surface 81a and the two side walls 81b, 82a of the air cleaner case 76, and the discharge port 81q for the oil, water and the like is provided at an end portion of the oil passage 90. [0041] The oil passage 90 is formed in the air cleaner 18 by the lower surface 77a of the air filter element 77, the bottom surface 81a of the air cleaner case 76 and the two side walls 81b, 82a of the air cleaner case 76, and the oil and the like are caused to flow from the oil passage 90 to the discharge port Blq, whereby the oil and the like can be discharged with a simple structure without specially forming a passage in the air cleaner case 76, and the oil passage 90 can be easily formed. [0042] In addition, since there is no need to provide a chamber as in the conventional art, there is no need for bolts or partition wall, the number of component parts can be reduced, and production cost of the air cleaner 18 can be reduced. Besides, fastening of bolts for forming the chamber is not needed, so that the number of assembly steps of the air cleaner 18 can be reduced, assembly is facilitated, and assembly cost of the air cleaner 18 can be reduced. [0043] Further, when the bottom surface 81a of the air cleaner case 76 is spaced downwards from the air filter element 77 by a sufficient distance, namely, the predetermined spacing HL so that the oil flowing on the bottom surface 81a of the air cleaner case 76 does not adhere to the air filter element 77, the air filter element 77, particularly the filter paper 77b, is not stained by the oil or the like, so that exchange interval of the air filter element 77 can be prolonged. [0044] Incidentally, in FIG. 6, the communication hole 103 into which the oil mist in the air cleaner 18 flows is provided on the side of the air filter element 77 with respect to the connecting tube 17; however, this arrangement is not limitative, and the communication hole 103 may be provided in the case main body 81 on the side opposite to the air filter element 77 with respect to the connecting tube 17. In the latter case, the communication hole 103 is spaced from the air filter element 77, so that it is possible to more securely prevent the oil mist coming out of the communication hole 103 from flowing to the side of the air filter element 77. [0045] [Effects of the Invention] The present invention, constituted as described above, displays the following effects. The air cleaner structure for vehicle according to claim 1 resides in that the air filter element is disposed at a predetermined upward spacing from the bottom surface of the air cleaner case fronting on the inside of the clean side of the air cleaner, the passage is formed by the lower surface of the air filter element, the bottom surface of the air cleaner case and the two side walls of the air cleaner case, and the discharge port is provided at an end portion of the passage. Therefore, the oil and water in the air cleaner case can be made to flow from the passage on the bottom surface to the discharge port, and the oil and the like can be discharged with a simple structure without specially forming a passage in the air cleaner case. [0046] In addition, since there is no need to provide a chamber as in the conventional art, there is no need for bolts or partition walls, the number of component parts can be reduced, and production cost can be reduced. Besides, fastening of bolts for forming the chamber is not needed, so that the number of assembly steps can be reduced, assembly is facilitated, and assembly cost can be reduced. [0047] Further, when the bottom surface of the air cleaner case is spaced downwards by a sufficient distance from the air filter element so that the oil flowing on the bottom surface of the air cleaner case does not adhere to the air filter element, the air filter element is not stained by the oil or the like, and the exchange interval of the air filter element can be prolonged.
